Centos6.8安装python环境，,一.安装步骤1.检查

一.安装步骤
1.检查系统python
CentOS 6.8自带的是Python 2.6.6，yum中最新的也是Python 2.6.6，只能下载Python 2.7.12的源代码自己编译安装。如下图：

安装Development tools
#yum -y groupinstall "Development tools"
安装编译Python需要的包
#yum install zlib-devel -y

#yum install bzip2-devel -y

#yum install openssl-devel -y

#yum install ncurses-devel -y

#yum install sqlite-devel -y

#yum install tcl-devel –y

#yum install tk-devel -y
4.下载并解压Python 2.7.12的源代码
#cd /opt
#wget --no-check-certificate https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz
#tar xf Python-2.7.12.tar.xz
#cd Python-2.7.12

#tar xf Python-2.7.12.tar.xz
#cd Python-2.7.12

编译与安装Python 2.7.12
#./configure --prefix=/usr/local
#make && make install
6.将python命令指向Python 2.7.12

cd /usr/bin

#rm –rf python

#ln -s /usr/local/bin/python2.7 /usr/bin/python

#python –version

由上图所示 python2.7安装完成
